Sebastian Professional Dark Oil Lightweight Mask

My hair was very processed, dehydrated, it broke frequently, it got very hard after bathing and a friend recommended this mask to me and I can say that after using this mask for a whole month my hair changed too much, that's why I really recommend it. My hair looked very healthy.

One of the best's masks that I've used.

This is bananas good. Why isnt it a best seller??? I have long, medium-thick, wavy-curly hair and this is my new holy grail conditioner. I use it 2-3x a week and my hair looks fantastic, luscious, not weighed down for all the moisture it gives. Obsessed.

Does a better job than most on my very dry hair

I went on a hair mask tear last year trying to find something that would finally work on my extremely long, coarse, wavy, tangly, unruly hair, and this is it! I tried so many others that made all the "best" lists—Kérastase Discipline, Olaplex No. 8, Verb Ghost, Innersense, Mixed Chicks, It's a 10, Pureology Hydrate, but the Dark Oil Mask outdoes them all by bounds. I was a little worried seeing "lightweight" in the name—I thought it might not work for my can't-be-tamed thick long hair after so many other failed hair mask attempts, but I love the hair oil in this line so I decided to give it a go, and I'm so glad I did. You get an extremely generous amount compared to other mask (it's a huge container), detangles better than anything I've found, moisturizes very well, thick salon-quality silky product, and smells amazing (a boutique worthy scent—sort of a unisex fresh meets a hint of vanilla?). My hair could soak up a full tub of almost anything else in one wash, but this lasts! Works great too for me (although not its intended use) as a styling cream/leave-in if you're throwing your hair in a bun or braids to really smooth things out. Absolutely worth it (try the Sebastian Dark Hair Styling Oil too!)
